Haven't "Finance" heard of Google, then?
Other thoughts are:- presumably users
want these pumps ... so why not get them to justify the expenditure (of tax-payers' money)? Isn't this the sort of thing that PASA, MHRA

Hint: speak to the companies likely to bid ... they will have all the data (and more) your little heart desires.
